Hey Eric,
You wouldn't believe some of the mails we get from users
I'll try and find some of the funnier ones if I get some time.
I think it amounts to nothing, I mean we've been threatened to be sued like once a week for 7-8 years and not once has it actually happened.
As for badmouthing your site.....in this case, I believe they are just advertising for you for free....if they complain to 20,000 yahoo people, maybe 1000 of them will go checkout the site
